Question

A piece of insulated wire is shaped into a figure eight as shown
inFigure P23.10. The radius of the upper circle is 5.00 cm and
thatof the lower circle is 9.00 cm. The wire has a uniform
resistanceper unit length of 3.00 / m.
Auniform magnetic field is applied perpendicular to the plane of
thetwo circles, in the direction shown. The magnetic field
isincreasing at a constant rate of 2.14T/s. Find the magnitude and
direction of the induced current in thewire.I =
T

The current is clockwise in the lowerloop,
which becomes clockwise current in the upperloop.

The current is counterclockwise in
thelower loop, which becomes clockwise current in the
upperloop.

The current is clockwise in the lowerloop,
which becomes counterclockwise current in the
upperloop.

The current is counterclockwise in
thelower loop, which becomes counterclockwise current in the
upperloop.
